The perl pages have an incorrect content length header for http responses. This
results in the last couple bytes being cut off my strict http clients.

Test Plan:
1. choose a *.pxt page that you can access without authentication.
2. run "curl 'http://your.url.pxt' > lengthtest"
3. Verify that the file created includes all the necessary characters (ends with
</html> is a simple check)

Current Results:
http://schroeder.rdu.redhat.com/help/contact.pxt ends with </html

Expected Results:
ends with </html> linefeed
